15. Subsequent Event

On September 4, 2013, our Board of Directors authorized the repurchase of up to $25.0 million of our common stock, par value $0.01 per share, through a share repurchase program. The repurchase program terminates January 31, 2015. Under the program, management is authorized to repurchase shares through Rule 10b5-1 plans, open market purchases, privately negotiated transactions, block purchases or otherwise in accordance with applicable federal securities laws, including Rule 10b-18 of the Securities Exchange Act of 1934. This share repurchase program does not obligate us to acquire any specific number of shares and may be suspended or discontinued at any time. All repurchases are expected to be funded from our current cash and investment balances. The timing and amount of shares to be repurchased will be based on market conditions and other factors, including price, corporate and regulatory requirements, and alternative investment opportunities.
